17. Malfunction code
17.1 Alert code
• The machine's CPU performs a self-diagnostics function that, on detecting a malfunction,
gives the corresponding warning code and maintenance call mark on the control panel.
17.1.1 Alert code list
• If an image stabilization fault occurs, the corresponding warning code appears.

Item
• When adjusting the IDC sensor, output voltage
detected for all sample patterns are specified value or
more.
• When adjustment is complete, sensor's output voltage
with selected light intensity is specified value or under.
• During image stabilization (gamma correction control),
detected output value for IDC sensor did not go below
threshold (half the value of what is detected by IDC
sensor on the belt surface) for three consecutive times
(position of the pattern end is not detected).
• During image stabilization (gamma correction control),
sensor's output value of each color for hyper 0 grada-
tion after the primary approximation is half the detec-
tion level on the belt surface or under
• All density readings taken from the density pattern pro-
duced on the transfer belt are 1.0 g/m
photo receiver output) or less during max. density
adjustment (Vg/Vdc adjustment).
• The output from the color PC drive main and sub sen-
sors remains unchanged for a continuous period of
1,000 ms while the color PC motor is turning stably and
the lock signal is active (LOW-0).
sors remains unchanged for a continuous period of
1,000 ms while the transport motor is turning stably and
the lock signal is active (LOW-0).
